电动汽车无线充电电磁环境安全性研究
Electromagnetic Enrironment Safety Study of Wireless Electric Vehicle Charging
摘要
Abstract
In recent years, wireless power transfer has been widely applied. One of the main applications is electric vehicle charging. To effectively evaluate the safety of human body in the electric vehicle (EV) charging electromagnetic environment, 3D electromagnetic simulation software is used to build the electromagnetic environment of the electric vehicle charging model. Accordingly, the electromagnetic exposure problems of the main tissues are studied. The results show that different tissues in human body have different absorption of electromagnetic waves because of their different electromagnetic parameters. Herein, the maximum current density is 20.058mA·m?2, the maximum power density is 1.22×10?5W·m?2, and the maximum SAR value is 4.37×10?7W·kg?1, which are all below the safety limits of ICNIRP guidelines. It is shown that the human body in the electromagnetic environment is basically safe.关键词
